Beit known that l, GEORGE B. MX, acit-i.v

zen of the United. States, residing in the borough of Manhattan` city of New York, State ot'Newk York, have invent-ed certainnew and useful lm provemen ts in Lifters forCoal-Wagf.

ons, rizo., of which the following is aspecitication, reference being had to the accom pauying drawings, forming a part hereof.

'Coal is now commonly delivered to retail` customers in .wagons providedwith chutes, through which the coal is allowed to run directly to the coal-hole or into baskets,which are then lifted onto the shoulder and carried to the bin into which the coal is ultimately delivered.

sistance is not only a matter of some difculty, but it. frequently result-s in injury to the person who lifts it'through strain and otherwise. l s

It is the object of this invention to produce au auxiliary lifting device which can be ap-k chutes, butobviously maybe applied in other.

places where the load to be carried on the shoulder must be raised from a low level.

The device comprises a suitable spring in which energyl may be stored ina convenient manner by the operatorby means of a lever to which the load to be lifted is afterward connected, suitable means being also provided to retain the lever in anyy desired position for` convenience in placing the load and in removing it. l

The invention will be more fully described hereinafter with reference to the accompanying drawings, in which it isillustrated in a convenient and practical form,andin'which-v Figure l isarear elevation of a coal-Wagon to which the lifting device is'v applied, Athe wagon-wheels beingindicated by dotted lines. l

Fig. 2 is a view inl front elevation of thelifting device shown in Fig. l, but 011 a larger scale. Fig. 3 isla view ol' the same in side 'lhe lifting olf a full basket ofv coal from the level ot' the ground withoutas-l ot' the saine'in"parts?y vious that in s oinecasesafsin'gle lifting-lever elevation; c Fig. {11's'adetail'section1al View and its associated partsvmightbe employed;

buttor conveniencein `use vwith chute-delivery coal-wagons,.dsc.,-` two such lifting-levers forming a frame 'arepreferably employed. Q

- As yrepresented in the drawings',a\ tubular rbracket d is arranged to be supported up'on the wagon-bodybybracket-arms which are secured to such body, thetubular `bracket d having studs e, which enter holes-in the ends of the bracket-arinsfau d are securedtherein by removable pins e', `the,bracket',.with its attaehed parts, being thus readily removable from the wagongifdesired. Loosely mounted' on eachV end of the tubular bracket dare housings h, to which as hubs levers bare attached. `Vllithinthe.housings are stout` coiled springs a, the inner ends ofwhichare se. cured to the bracket d and the outer ends to their respective housings h. The levers b are each provided with slots jo and recesses rto engage a'carrier-frame, which latter consists, preferably, ot' agplatforin t, uprights u, and a strap c, this'construction providing a simple and convenient seat for a basket w. The

-u'prights u are provided on their upper ends with studs s to engage any of the recessesr,

and said studs mayhave enlarged ends or heads to prevent theirdisengagement with the slots p. In this waythe'frame isfeasily adjusted in the desired position on thelevers, and, as the latter are moved upward the frame, with itsfload, isalways carried in a vertical position. n y

Mounted on the ends of a rod h,fwhich vis located withinthe 'bracket d'andserves as' atie-rod to hold the housings and ylevers on the bracket, are ratchet-wheels '7), which move. with the .levers and housings, being held.

tightly against the same by nutsj, threaded on the ends of the rod h', the rod within the threadedyportions being squared to tit similar holes'in `the leversand ratchet-wheels.v In

operative relation with each ratchet-wheel is a double-acting pawl m, bywhich the levers may be locked from movement in either direction While being free to move in the other. The pawls are rigidly secured to a rod Z,

roo

loosely mounted in standards konthe bracket (l. feights n, loosely mounted on the ends of the rod l, may be thrown to either side of the pawls to determine which side of the same shall engage the ratchet-wheels, pins o being provided on the pawls as rests for said weights.

'lhe operation of the lifter is as follows: The levers and carrier-frame being in the position shown in dotted lines` in Fig. 1, the weights n are shifted from sided; of the pawls lo side y of the same. The levers are then lnoved down by the operator lo Ille position shown in full lilies, and a basket is placed in the carrier-frame and filled by means of the chute z. When it is desired to raise the basket, the position of the pawls is reversed by shiftingr the weights` and a part. or the whole of the weight of the load is overcome or connterbalanced by the pnllof the s[,i'ing,enabling the operator` to place the basket upon his shoulders easily and conveniently.

I clailn as my invention- 1. The combination with a coal-delivery or other wagon, of a lit'tersecnred to said wagon and comprisingr a spring, a lever connected to the spring, and means on the lever to engage a load, substantially as described.

2. The combination with a coal-delivery or other wagon, ot' a lifter secured to said Wagon and comprising a fixed bracket or support, a coiled spring.;r one end of which is secured to said bracket, a lever to which the other end of the spring is secured, and means on the lever to engage a load, substantially as described.

In a lifter, the combination with a lever adapted to engage the load, and a spring: in operative connection with said lever, of a ratchet-Wheel secu red to said lever at its fulcrum and a do11hleacting pawl in operative relation with said ratchet- Wheel, substantially as described.

4. The combination with a coal-delivery or other wagon, of a lifter secured to said Wagon and comprising a fixed bracket or support, a coiled spring one end of which is secured to said bracket, a lever to which the other end of the spring is secured, a ratchet-wheel secured to said lever at its fulcrum and a double-acting pawlin operative relation with said ratchet-wheel, substantially as described.

5. The combination with a coal-deliveryor other Wagon, of a lifter detachahly secured to said wagon and consistinpr of a fixed bracket or support, a coiled spring at each end of said bracket the inner end of each of said springs ,being secured to the same, housings for said
